Filed construction activity

Rent-stabilization signals

NoBuilt before 1974 (2000)
NoSix or more residential units (3)
No421-a / J-51 tax benefit on the current tax roll

0 of 3 signals present. None of the common signals are present — stabilization is unlikely (though never impossible). The definitive answer for any unit: request its rent history from NYS Homes & Community Renewal (free, at hcr.ny.gov).
